The skull is a hard and indispensable bone in the human body, which plays a pivotal role in the normal operation and health of human life activities. Once a cranial defect occurs, it is obvious that the patient’s appearance will be seriously damaged, some will be collapsed, some will be bulged, either way, the patient will become less confident and have a deep sense of inferiority; in addition, without the protection of the skull, the brain tissue is easily damaged, which will easily lead to abnormal cerebrospinal fluid circulation, blood supply disorders and other problems. The main purpose of the surgery is to replace the defective cranial bone with a material similar to human autologous cranial bone, to repair the bone window of the defective part, to realize the integrity of the cranial bone again, to restore the cranial cavity confinement, to maintain the physiological intracranial pressure stability, to reduce the occurrence of cranial defect syndrome; through the defect repair, to achieve the symmetry of the head shape Through the defect repair, the head shape is symmetrical, the appearance is natural and beautiful, and the patient’s inner confidence is improved. In neurosurgical guidelines, generally 2-3 months after debridement surgery, the defect diameter is greater than 3 cm, which is in line with the indications for surgery, and the patient needs to be repaired in time. Although cranial repair is a routine neurosurgical procedure, it is also a large craniotomy, and it is recommended to go to a large public hospital for surgery. It is reported that many hospitals commonly carry out titanium mesh cranial repair, selecting titanium mesh as the cranial implant material, but because of the implantation of titanium as a metal material and the use of covered repair, there are many postoperative complications such as rejection infection rate, wear and tear skin material exposure. In view of this, after years of clinical exploration and summary, the Civil Aviation General Hospital upgraded and improved the original cranial bone repair technology to form a mature technology – peek material cranial bone repair plastic surgery, which uses the new peek as the cranial bone repair implant material, greatly reducing the postoperative rejection rate, infection rate; at the same time, using embedded repair In addition, the innovative introduction of plastic concept, combined with the unique mesh aperture design and unique tissue separation and reset technology, effectively avoid temporal muscle atrophy, ensure the activity of the tissues, ensure the symmetry of the postoperative head shape, and achieve the purpose of natural and beautiful appearance. Warm tip: The above is the detailed introduction of what are the hazards of cranial defects, hope it is helpful to you. It is suggested that patients with cranial defects should go to regular hospitals to take appropriate repair materials in time to restore health as soon as possible.
